Show HN: Watchman – Capturing Invisible B2B Buyers with AI (Built with 4 PhDs)

Hi HN!

We are a small team that has been bootstrapping an AI‑native solution to help B2B companies capture hidden buyers by automating the identification, research, and qualification of anonymous website visitors with just one line of code.

Here is a quick product video: https://youtu.be/ptGYkWbCJN4?si=hLvZGVbYMYbxzNwg

Four of our five team members hold PhDs in statistical inference or related fields, and we came together because we believe that modern GTM tools excel at collecting signals but fall short on the inference layer. Simply plugging an LLM into a dashboard won’t cut it – the real breakthrough requires a far sharper lens and far stronger predictive engines than legacy platforms provide. That’s exactly what we’re building.

The current version of Watchman transforms anonymous web traffic into pipelines of qualified accounts and person‑level leads. Our agent identifies, researches, and qualifies anonymous visitors, syncs those enriched leads into tools like HubSpot and Salesforce, sends live notifications to Slack and email, and supports unlimited users so you can invite your entire team.

We’d love for you to try it out and share your feedback! Check it out at https://joinwatchman.com

This seems like an interesting approach and automating visitor qualification is definitely useful. But quick question though, once you drop in that “single line” of code, how soon can a team expect to see their first qualified leads?

That’s amazing and horrifying. Do you want to use an Internet where every website is tracking you like this? Why would you release this?

Thanks for bringing this up. We don’t invade personal privacy. We only enrich qualified, high‑intent buyer intelligence, and we do so solely for B2B. Some GTM vendors have experimented in this space, but we focus on AI‑native demand inference with far greater precision and efficiency, while always following strict safety and privacy practices.

At first glance:

If I visit one of your customer’s websites, have I given them permission to collect and process my personal information? Do you have a way to avoid collecting this PII for people in GDPR countries? If I were to send you a CCPA request, do you have a mechanism to completely avoid storing my information?

I think this product is inherently incompatible with personal privacy, although I’d be interested in hearing why I’m wrong.

This is some fascinating mental gymnastics.

Because it’s profitable.

Alas.

And so is dumping waste into rivers, but I hope people will continue to tell the people doing it that they’re wrong for doing so.

Profit alone isn’t the motivation. Unlike polluting rivers, our goal isn’t to externalize costs onto society or the environment. We see a real problem: B2B teams waste massive time and budgets chasing unqualified leads, spamming prospects, and burning through acquisition dollars. By delivering truly high‑precision demand intelligence, we help businesses focus only on the buyers who actually want to talk, cutting down on unwanted outreach and wasted resources.

In other words, our goal is to create efficiency and reduce friction for buyers, sellers, and the planet rather than offloading harm onto someone else.

Guys, you're evil and I sincerely hope your business does not take off.

What study has been performed to qualify the cost your product externalizes on the unsuspecting user, with their expectations of privacy, human dignity and all, o' great team of PhDs?

We’re not externalizing costs onto users because our demand inference uses only qualified, high‑precision intelligence to eliminate massive spam and irrelevant outreach that wastes everyone’s time and erodes trust. We conducted user interviews upfront to understand these pain points before we started building. By focusing solely on B2B, we reduce noise, protect privacy, and respect people rather than treating them like targets.
